SIDE FRAME FOR GAR-TRUCKS.

Application filed \Tune 14.

Trucks, of which the following is a full, clear, and exact specification.

This invention relates more particularly to that class of side frames for car trucks in which the bolster springs are situated at about the mid-length thereof in a seat or recess between the upper and lower edges of the frame,

I and of this class it has especial reference to cast frames as contradistinguished from pressed or composite frames. In this form and class of side ones the presence of the spring recess thus disposed renders the structure weak and without adequate stillness and rigidity against vertical strc at the very point where the greatest strength is required.

One of the objects of the invention, therefore, is to Overcome this objectiouand provide an improved and durable .form of east side frame which will possess the -journal boxes at the ends of the side frames.

A still further object of the invention is to provide an improved brake beam hanger whereby the brake beam may be readily relcascd and removed if desired. I

' With these ends in view the invention consists in certain features of novelty in the construction, combination and arrangement of parts whereby the said ob- 1 jects and certain other objects, which will hereinafter appear, are obtained, all as fully described with rcfercnco to the accompanying drawings and more par ticularly pointed out in the claims.

In the said drawings l igure .l is a side elevation of a car truck side frame embodying this invention; Fig. 2 is a plan view thercof with one end in horizontal section on the line 2 Fig. 1.; Fig. 3 is a vertical crosssection on the line 3-3 of Fig. l; and Fig. 4 is a detail side elevation of the brake beam hanger detached.

It is customary in the construction of side frames for car trucks, of this character, to locate the springs for the bolster at about the mid-lcngth of the frame and in such position and relation to the fra-nm that the upper ends of the springs will be below the upper edge of the frame. To do this it is necessary to form at that point a recess which is indicated at 1, and this of course greatly weakens the frame at the very point where the Specification of Letters Patent.

greatest strength against vertical stress is required. In this exempliflcation of the invention, the frame in side elevation has the general form of a truss, or approximately diamond shaped, and its lower edge is cast with an integral longitudinal rib 2, while its upper edge is formed with a similar rib 3, both of these having their greatest diameters or width-arranged horizontally, and they are connected together by a vertical web 4 in which apertures 5 may be formed at both sides of the spring recess 1 for the sake of economizing the material.

- Between these apertures 5 and below the recess 1 is cast integrally with the web 4 a spring seat or box (5 which projects equal distances from the sides of the web 4, as better shown in Fig. 2, so that the main body of the side frame will be central with respect to the spring box and will divide the box into two seats or compartments of equal dimensions. The combined height of the springs and the bolster, all of which should be contained between tbe upper and lower ribs 23 of the side frame, is such as to make it necessary to locate the bottom of the box 6 very close to the bottom rib 2, and as a consequence the .mainwob l of the frame upon which greatest reliance is placed for resisting vertical stress is almost wholly destroyed or removed at this point.

, In order to compensate for this and to at the same time afford simple and eflicient means for holding the usually employed, the device is cast integrally with a central partition web 7, which, as bettorshowu in Fig. 3, rises as a continuation of the web 4 and the bottom of the spring box to substantially the level of the upper edges of the boy, thus amply reinforcing and stiffening the side f ramc at the mid-length where the recess 1 is formed and at the same time leaving ample room above for the introduction of theend of the bolster. Imme' diately above'the reinforcing web'7 the top rib 3 may be formed with a depending flange 8 in the same plane as the web 7, which adds considerable strength to the casting at this point without materially increasing the weight or interfering with the movement of the bolster. Neither the bolster nor the springs have been shonw in connection with the side frame, but as their construction and position are well understood in this art, his not necessary to illustrate and describe them in detail; suffice it to say that the springs are ordinary vertical coil springs, four in number, arranged two on each side of the partition web 7 and-resting upon the bottom of the box 0, while thc'bolster projects through the recess 1 and has suitable support upon their upper ends. The structure at its rniddength is further strengthi ened and reinforced to compensate for the loss of strength incidental to the presonce of the recess 1, by providing the upper edges of the box 6 with a surround ing lateral flange or web 9, and this is carried into and cast integrally with vertical flanges or webs 10 at the springs accurately in place in box, four springs being vertical edges of the recess 1 on both sides of the web 4,

thus forming with that portion of the top rib S'immediately above the recess 1, and the partition web 7,.a recclamps for this purpose of two different forms, both of which, if desired, may be employed on the same side frame, orthe frame may be provided at both ends with either form. Reie'rrin'g to the form sh own on the left in Fig. 1, it will be seen that it consists of two integral jaws -1314,'which project horizontally, so that the journal box 11 may be inserted from the left hand side between them. The upper jaw is stiffened at the proper point by means of avertical rib 15, and the lower jaw with a similar-rib 16. Between the extremities of these jaws passes a vertical bolt 17 which fits in suitable seats or retainers 18 on the outer side of the box 11. The opposite end of the side frame may, of course, be provided, if desired,'with a similar means for holding the box 12, or it inay be provided with the form of means shown in Fig. 1, and which it will be seen consists of an upper jaw 19 undeuwhich is situated the box 12, and by which the side frame is supported upon the box, and below the box and againstthe outer sidethereof is arranged an L shaped casting 20 ,which fits against the under side of the rib 2 and also against the under side of the jaw 19. This L shaped casting 20 is held in place by an L'shaped bolt 21 which passes through the overhanging-extremity of the jaw 19 and also through the boss 22cast integrally with the web 4 and rib 2. The upwardly extending extremities of this bolt 21 are provided with nuts 2324 or other suitable means for.placing it under strain in an upward direction and thereby clamping thev casting 20 and box 12 in place. V

' On one side of the spring box 6 is formed a lip or laterally projecting flange 25, and over this is fitted body 26 of the brake beam hanger which is also formed with two arms 27 carrying perforated lugs 28 for the attachment of the brake beam. This hanger is removable from the lip of flange 25in a lateral direction, but when in use is held in place by a pin 29 passing downwardly .thro ugh the body 26 and the lip 25 and held against upward displacement bya cotter 30,- so that 'when desired the hanger may be released from below and the brake beam readily dropped down and removed if desired.

In order that the invention might be understood by those skilled in the art, the details of an exemplification thereof have been'thus specifically described, but

What I claim as new and desire to secure by Letters Patent is:
